After Blue City Invested in 'Green' Snow Plows - They Get Hit With Harsh Reality

Bad idea...

pjnewsletter.com

By Mick Farthing| November 13, 2023

What’s Happening:​

Since Joe Biden entered office, Democrats have been pushing for a “green” revolution. Washington has dumped billions into green technology–with middling results.

Believing this was the future, some blue states aggressively started transitioning to “alternative” energy. New Jersey installed wind turbines off the coast–which some claim are killing whales.

Another blue state thought it was time to switch to electric snow plows. But with the first whiff of snow, they learned a harsh reality.

From Breitbart:
New York is staying with traditional diesel-powered snow plows after rejecting electric vehicles proposed as a replacement…
Essanews reports the move has been a failure. The reason was given as a simple lack of power…
Consequently, the electric vehicle’s power supply was insufficient for the demands of a New York winter, known for its heavy snowfall.

New York City considered buying electric Mack trucks for the upcoming winter snowfall. The goal was to equip these trucks with snow plows while removing garbage. But they quickly learned these “clean” electric trucks could not provide enough power to do the job.

Studies showed that electric vehicles needed to be in “constant movement,” which made collecting trash impossible. The buildup of snow in front of the vehicle proved to be too much for the electric motors.

We remind you, snowplows… plow snow, so there will always be resistance.

The trucks’ power supplies could not meet the demands of a New York winter, which often sees large dumps of snow, especially in January and February.

The city has been forced to ditch this plan and stick with traditional diesel-powered snow plows.

Many have been critical of Democrats’ mad dash for “green” technology. Biden’s ban on drilling for oil and gas has seen dramatic increases in the cost of electricity. Car companies are losing billions after making too many EVs.

Americans are refusing to buy electric vehicles because they lack the range of a gas-powered car.

Critics have also questioned why Democrats are focusing solely on EVs when there are other viable alternatives. Diesel-powered cars use less fuel than regular gas-powered cars, yet they are overlooked by Democrats.

Fuel cell-powered cars have been largely rejected, in favor of EVs that put huge demand on the grid.

It is possible that Democrats are pushing EVs at the behest of corporate lobbyists, despite the best interests of Americans.

Key Takeaways:​

• New York attempted to switch to electric-powered snow plows.
• The EV trucks could not handle the job, as their power supplies were too weak.
• The city will stay with diesel-powered trucks to handle the snow.

Shaken and Stirred: When Bond Meets Suess–de Vries and Gnevyshev–Ohl

We argue that the most prominent temporal features of the solar dynamo, in particular the Hale cycle, the Suess–de Vries cycle (associated with variations of the Gnevyshev–Ohl rule), Gleissberg-type cycles, and grand minima can all be explained by combined synchronization with the 11.07-year periodic tidal forcing of the Venus–Earth–Jupiter system and the (mainly) 19.86-year periodic motion of the Sun around the barycenter of the solar system.

Shaken and Stirred: When Bond Meets Suess–de Vries and Gnevyshev–Ohl - Solar Physics

We argue that the most prominent temporal features of the solar dynamo, in particular the Hale cycle, the Suess–de Vries cycle (associated with variations of the Gnevyshev–Ohl rule), Gleissberg-type cycles, and grand minima can all be explained by combined synchronization with the 11.07-year...

link.springer.com

Abstract We propose a self-consistent explanation of Rieger-type periodicities, the Schwabe cycle, and the Suess-de Vries cycle of the solar dynamo in terms of resonances of various wave phenomena with gravitational forces exerted by the orbiting planets. Starting on the high-frequency side, we show that the two-planet spring tides of Venus, Earth and Jupiter are able to excite magneto- Rossby waves which can be linked with typical Rieger-type periods. We argue then that the 11.07-year beat period of those magneto-Rossby waves synchro- nizes an underlying conventional α − Ω-dynamo, by periodically changing either the field storage capacity in the tachocline or some portion of the α-effect therein. We also strengthen the argument that the Suess-de Vries cycle appears as an 193-year beat period between the 22.14-year Hale cycle and a spin-orbit coupling effect related with the 19.86-year rosette-like motion of the Sun around the barycenter.

A BIG NEW SUNSPOT GROUP: A large and active sunspot group is emerging over the sun's northeastern limb. This 24-hour movie from NASA's Solar Dynamics Observatory shows seven Earth-sized dark cores, with more to come:​

​

Newly-numbered "AR3490," the sunspot group is cracking with flares. Earth-orbiting satellites have registered three M-class flares and nearly a dozen C-class flares since the weekend began.​

The sunspot group is so large, it is affecting the way the whole sun vibrates. Helioseismologists used the tremors to detect this sunspot group while it was still on the farside of the sun. Their latest seismic maps confirm that we haven't seen all of it; some of the group is still wrapped around the edge of the sun. SpaceWeather.com​

Total number of sunspots has increased to 174 (85 of these are grouped into 10 active regions) NOAA forecasts for the next 24h: 99% chance for C flares, 55% chance M flares and 10% chance for X flares.

Sunspot complex AR3490-91-92 has a beta-gamma class magnetic field that poses a growing threat for M-class solar. Sunspot.​

SPECTACULAR 'CANYON OF FIRE' ERUPTION (UPDATED): A dark filament of magnetism erupted from the sun this morning (Nov. 22 @ 0600 UT), carving a deep 'canyon of fire' in the sun's atmosphere. First-look forecast models suggest that a CME emerging from the blast site will just miss Earth later this week. CME alerts: SMS Text

SOLAR CYCLE 25 ACTIVITY REPORT NOVEMBER 24_2023

MONSTER ERUPTIONS. Solar activity has been at moderate levels for the past 24 hours. On November 23 two M-class solar flares were recorded. The first flare has already been reported and came from an as yet unnumbered region.

X-ray Solar Flare: M1 at 0338 UTC the flare caused a Minor R1 radio blackout over Indian Ocean.

Second flare a M1 at 14:37 UTC from AR3490 (N21E11) the flare caused a Minor R1 radio blackout over Brazil

A SHARP INCREASE IN SOLAR ACTIVITY: Over the past week, sunspot numbers have increased almost 10-fold with dozens of dark cores now present on the solar disk. It is no surprise that solar activity has sharply increased as well. Just today multiple overlapping CMEs have billowed away from the sun:​

​

Analysts will have to spend some time unraveling these clouds to determine their trajectories. However, a NASA model already suggests one may be heading for Earth. The first, bright southerly CME shown in the movie above could hit our planet's magnetic field during the late hours of Nov. 25th. SpaceWeather.com​

There are currently 12 sunspot regions on the solar disk: AR3489, AR3490 AR3491,AR3492, AR3493, AR3494, AR3495, AR3496, AR3497, AR3498 and new regions AR3499, AR3500, AR3501

Total number of sunspots has increased to 176 (67 of these are grouped into 12 active regions) NOAA forecasts for the next 24h: 99% chance for C flares, 60% chance M flares and 10% chance for X flares.

Sunspot regions AR3490 and AR3500 have developed a beta-gamma-delta class magnetic field that harbors energy for X-class flares. AR3492 continues with a beta-gamma magnetic field that harbors energy for M-class flares.​

● Auroral Activity

The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. On November 23 Solar wind speed reached a peak of 537 km/s (Moderately high speed) at 23:23 UTC.​
